How do you troubleshoot Caching Errors in Java Runtime Environment?

I have run into Caching Errors while using JRE (versions 1.4.2 and 1.5.0, various updates) using Windows XP and IE6. The error screen has the title Error - Cache and appears when trying to download JAR files through a secure HTTP connection. The error reads: "Caching Error. Unable to store or update files in the cache." In the details box, the first line can differ:
java.net.SocketException: Connection reset
java.net.UnknownHostException: [followed by a URL]
java.net.ConnectException: Connection timed out: connect
I looked in the Java Control Panel to make sure that the "Enable caching" box is checked, and removed the proxy settings in IE. The user has sufficient rights on the computer to download files.
How does one go about troubleshooting these caching errors? Is there a reference document available? I could not find anything on the Sun site or anywhere else.
Any help would be very much appreciated.

I deleted c:\Documents and Settings\<user>\Application Data\Sun (the same as in Java Control Panel->Temporary Internet Files->Settings, but at higher level). After that and some machine reboots it worked.

Error initializing Java Runtime Environment. You may need to reinstall Flash.

...This is really annoying.

So I come across this post. Follow it exactly.
"Error initializing Java Runtime Environment. You may need to reinstall Flash."
I change the thingy in the file to Xmx1024M
"Error initializing Java Runtime Environment. You may need to reinstall Flash."
I come to the forums.
What do I do now?

Intro:
Finally I got near to roots of that mysterious Error
"Error initializing Java Runtime Environment. You may need to reinstall Flash."
So here is what I'm found out + Bugfix
JavaPatch for Adobe Flash CS5 / CS6...     Ver #1 [ 21.01.2014 ]
======================================
This is the fix the bug in Flash tell you all the time that
Java could not be loaded. The effect of this error is that
Actionscript will not work.
Flash gives a little misleading error messages that tells you that
"There is no Actionscript in the current Project"
background information:
The problem is that the Java Virtual Machine.dll demands on startup
250MB huge contiguous memory blocks, but the 2GB-Virtual address
space of the Flash.exe process is already filled with various loaded dll's
BEFORE you continue ensure that you install/copied JRE 1.8.0 update 31 to
%ProgramData%\Adobe\CS5\jre\
For testing check if ...Adobe\CS5\jre\bin\java.exe starts
(and shows a help about available commands)
The Patch is for 32-bit version only!
(however the problem is probably not in the 64-Bit Version - since there a process has a much large more 'space')
Well SIMPLE FIX / Workaround:
Use 64-Bit version of Adobe Flash !
TechDetails:
Java's JVM.dll loaded in Ollydebug - The patched / change bytes are red.
^-Note that String ASCII "NUMA page alloc..." - will be a great 'link' to easily find that location in other JVM-versions to applied the patch there. Open jvm.dll in Ollydebug open String Ref. Windows and search for the string...
Download instructions:
Right click on picture above and download it.
Drag/open the *.jpg in / into Winrar / 7-Zip
OR
Rename 'Flash-CSX-jvm-JavaPatch #1.7z.jpg' -> 'Flash-CSX-jvm-JavaPatch #1.7z' so you open it by doubleclick
-> My creative solution for that A-Dope-board missing 'Attach file feature'
Tested:
with Adobe Flash CS5 + JRE 1.8.0 update 31
More Techstuff:
Some of my notes that might be useful:
Note the memory is not real allocated in the way it can be use since to write or read from it is just allocated as
MEM_RESERVE like you see in the screenshot above. And freed just a little alter.
It seems that java just checks if it could possible the maximal the JVM is made for.
Note the problem is not that you have to less physical RAM installed.
It's more related how memory is organise.
Well in 32 Bit each process has 4GB (or well practically Windows limits this to 2GB).
0x00000000 to 0x7FFF0000
This space is virtual and not actually claimed (else you would very quickly run out of RAM) but it a kind of potential or Adress system. Na sorry that'll be to offtopic to explain all the basic's about memory.
Adobe Flash CS5 calls
jvm.dll!JNI_CreateJavaVM( OUT **p_vm, OUT **p_env, IN *vm_args);
The 'vm_args'
typedef struct JavaVMInitArgs {
    jint version; 00010004
1. /* user classes */
-D java.class.path=
C:\Program Files\Adobe\Adobe Flash CS5\Common\Configuration\ActionScript 3.0\;
C:\Program Files\Adobe\Adobe Flash CS5\Common\Configuration\ActionScript 3.0\asc_authoring.jar;
C:\Program Files\Adobe\Adobe Flash CS5\Common\"...
2. /* set native library path */
-D java.library.path=
C:\ProgramData\Adobe\CS5\jre\bin
3.
-D java.Home=C:\ProgramData\Adobe\CS5\jre
4. classpath append
-X bootclasspath/a:
C:\Program Files\Java\jdk1.7\jre\lib\ext\QTJava.zip
5. Headless mode is a system configuration in which the display device, keyboard, or mouse is lacking. Headless mode support has been available since the J2SE 1.4 platform.
-D java.awt.headless=true
    jboolean ignoreUnrecognized; 1
} JavaVMInitArgs;
So for any further exploration about this Java problem setting a breakpoint to 'JVM.dll!JNI_CreateJavaVM' will be a great startpoint

I keep getting this pop up.To view this web content, you need to install the Java Runtime Environment. How can I get rid of it?

I keep getting this pop up - To view this web content, you need to install the Java Runtime Environment. How do I get rid of it.

Most likely, you have a web plugin that depends on the Java runtime distributed by Apple, such as the Facebook video calling plugin or the "NexDef" plugin for watching baseball streams. If you no longer need the plugin, remove it. Otherwise, install Java.

Safari 8 error: "...you need to install the Java Runtime Environment"

Ever since upgrading to Yosemite and Safari 8, I continually get the error "To view this web content, you need to install the Java Runtime Environment" and, although I did do so the first time I got the error, and Java tells me I do have the latest version installed and running, I continue to get this error constantly.
Is there a way to stop this, or at least find out what content is causing it? I can't put my finger on any particular content that causes the error.

This procedure is a diagnostic test. It makes no changes to your data.
Please triple-click anywhere in the line below on this page to select it:
java -version
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
If the Apple Java runtime is installed and up to date, you should get three lines of output below what you entered, the first of which is this:
java version "1.6.0_65"
Is that what you get? You can then quit Terminal.

I keep getting this message.To view this web content, you need to install the Java Runtime Environment.

Every few minutes the message comes up on my screen. To view this web content, you need to install the Java Runtime Environment. Is the new iOS running with java. if not how do i stop messages?

Troubleshooting:
I have since unchecked the option Enable Java content on the browser in System Preferences > Java > Security - I will report back if the prompt still reappears, but I think it should be gone now.
Follow up:
I have since sent a feedback to Apple and I recommend you guys send it too, more people reporting will get Apple's attention on the issue.
Issue:
For me, this issue started after updating to Yosemite, I keep getting a prompt window on Chrome 38.0.2125.122 with a message "To view this web content you need to install the Java Runtime Environment, but I do have Java installed."
Hardware/Software:
Macbook Air Mid 2013 1.3Ghz 8GB RAM 120GB SSD / Mac OS X Yosemite 10.10

You need to install the Java Runtime Environment

I am sorry to ask this but for some reason the search feature won't work so that I can find the answer that has been posted to this question. So I guess there are two problem. I type in the question and I see that there are solutions to view but my computer won't go to the answer. I am just going to re-ask.
I get this error message every time I turn the computer on "To view this web content, you need to install the Java Runtime Environment." I have the latest and I have only gotten this after installing Yosemite. Can you please tell me how to get this to go away? Thanks Marilou

Error initializing Java Runtime Environment

"Error initializing Java Runtime Environment. You may need to
re-install Flash"
Has anyone else been getting this error message?
Re-installing is a problem because I work in a HUGE company
with LOTS of red tape and I don't have access to the original disks
to re-install.
I can't even load my file anymore without getting the error
and once opened, I can't even do a "check script" without getting
the error. I've even tried to load earlier versions but I'm still
getting it!
Any workaround or am I doomed to wait for an IT guy to show
up in a day or two?
"Deadlines? WHAT DEADLINES??!!"

I have been experiencing this unpleasant phenomenom also, appears that we aren't the only ones.... have you had any success in resolving this issue? I am just starting the process of working through the error message and any information would be appreciated.
The tech Adobe support was not helpful and suggested using these forums.

HT202912 I get the message "To view this web content, you need to install the Java Runtime Environment" Do I need two versions as this article suggests?

I just upgraded to Yosemite on my 2010 MacBook Pro. When I reboot I get the message "To view this web content, you need to install the Java Runtime Environment" and I've also seen the same pop-up once while running OpenOffice. And now while composing this post.
Yes - I followed the link and installed the Oracle version of Java, version 8, and the test page confirms that I have the current version running.
I read some threads on discussions.apple.com but didn't like the answers.
I found this: http://www.macworld.co.uk/how-to/mac-software/advanced-tips-for-mac-os-x-yosemit e-3582877/
and tip # 10 seems to answer my question.
Anyone else have experience on this?

Most likely, you have either the Facebook video calling plugin or the "NexDef" plugin for watching baseball streams. Both depend on the Java runtime distributed by Apple. If you no longer need the plugin, remove it. Otherwise, install Java.

Error Help: Flash CS5 Error initializing Java Runtime Environment...

Hi im on a Win 7 64bit system (Clean install), I just downloaded the Flash Pro CS5 trial today - however when I start the program I get the following message as soon as the UI pops up and prevents me from running AS3 code when compiling files:
Error initializing Java Runtime Environment. You may need to reinstall Flash.
All I did was run the program. I tired updating it (update worked but still got the message at start up), I tired installing and uninstalling it, I tried uninstalling and installing different versions of Java and various existing solutions.
Also I used Adobe's clean up Script for CS5.
Does anyone know the answer to eliminating the error message?

Well this is a very old post but this error appear again in CS5.5, then I think is helpful retake this post
In Flash CS5.5 the issue is solved editing the file:
"c:\Users\current user\AppData\Local\Adobe\Flash CS5.5\en_US\Configuration\ActionScript 3.0\jvm.ini"
and lowering the Xmx128m to 128, some times this must be rised to compile large applications with a huge amount of AS3, or to use some Flex 4.5 libs from Flash Professional
I hope this help to CS5.5 users.

Java Test indicates that Java 6 is running well on my Mac. But when trying to run online applications the mentioned error message appears.
Thanks for your help!

Hi, Thanks for that further bug description In Your Last Message That Describes The Problem I Am Having perfectly and is exactly the same for me.
unfortunately that fix for my camera Powershot G6 does not work or apply as the view pictures switch is different on G6 is not usable during download as once you plug in DC/USB cable it turns off, and makes no diff and problem still exists exactly as you just described.
thanks anyways "Selz Boy"
it has been 17 days since apple promised to get back to me within 3-5 days hopefully with a solution, but I have still not heard from them.
They blew me off, i guess, probably i will have to wait for new Yosemite OS update, which they pre-warned me could take as much as 6 months.
I cannot believe apple released this new update with such major bug issues for camera downloads and that horrible "Photos" pgm which has all sorts of downgrades in features, usefulness and new bugs compared to iPhotos which I just finally got used to and was much better software.
I am starting to lose faith in Apple and I am getting that Microsoft "FEEL" like I used to have when I was a PC user, which was why I originally switched to Apple computers in first place.
Oh well got my fingers crossed here.
Thankfully the memory card reader solution is working well, but cost me $45.

Os x yosmite shows this message at startup: To view this web content, you need to install the Java Runtime Environment.

so I've just downloaded and installed OS X 10.10 YOSEMITE on my mac this morning and I find the design refreshing, however when I do a reboot of my mac this popup message always shows up: To view this web content, you need to install the Java Runtime Environment. here's a screen shot of it
it is really annoying, and quite bothering on my part. I tried clicking the "more info..." tab as instructed by the popup/ notification, which led me to the webpage of java, and this is a screenshot of what I got
so I've downloaded the .dmg file of the Java 8 update and installed it on my computer, did a check on my safari browser settings to see if the Java plugin is activated and, it is. Hoping that that the trick I rebooted my mac again and voila! the same popup appears again. I hope you could help me on this one guys, any suggestions for a quick fix would be greatly appreciated. Thank you.
Here are the specs of my mac:

This is a user forum. Apple probably monitor it but they are not on here answering questions.
Not sure what you mean about the hidden information-i mean cheese how much info is 'gleaned' across the net and its nothing to do with the OS and don't get me started on the behaviour of some OSs!. You can set your machine to not give feedback to Apple.
Not sure what does not convince you in what Casey Rey said-its a fact there is a download. Download it don't download it ,what is you want Apple to explain? They made a decision not put JRE on OS X by default -i think there might be some licensing thing about it with Oracle going on. If you need it you need it if you don't you don't. Its like saying you wont install MS Office unless they explain why thats not on the machine by default.
Who sold you the machine with the faulty screen? Apple on line? The Apple store? An Apple Dealer? How long have you had it? If i buy a Ferrari with a dent in the door and i knew it had a dent in the door it would be funny to say 'when this Ferrari breaks i am switching back to Porsche because they don't have dents in the door'
